Description

Embodiments of the present invention relate to shaving blade cartridges and shavers having such shaving blade cartridges.

In particular, the invention relates to shaving blade cartridges.

The shaving blade cartridge is a housing extending along a longitudinal axis, a top surface, a bottom surface opposite the top surface, and a longitudinal direction along the longitudinal axis between each of the top and bottom surfaces. A housing having first and second longitudinal surfaces extending therethrough, the housing having a through hole extending between the top and bottom surfaces through the housing in a direction transverse to the longitudinal axis; At least one cutting blade having a cutting edge extending along the longitudinal axis, disposed in the housing between the first and second longitudinal faces, and a clip for holding the at least one cutting blade in the housing And a clip having a first leg, a second leg, and a clip body extending between the first and second legs.

The through hole is neither a groove nor a slot. A through-hole in a housing is an opening that extends through the housing from the top of the housing to the bottom of the housing and is completely surrounded by material when viewed from the top or in cross section.

Patent Document 1 discloses a razor having two clips, and each clip includes a pair of legs extending through a pair of through holes provided in the housing. The two pairs of through-holes in the housing require significant structural modifications of the known cartridge housing. Moreover, assembly of the clips can be difficult. In fact, during the manufacturing process, both legs of the clip must accommodate two different through holes, which requires tight tolerances to be applied to the clip and to the through hole. To do.

Patent Document 2 discloses a cartridge having a clip that holds at least a blade. The clip disclosed in Patent Document 2 surrounds the housing and is housed at least in a groove provided in the housing. Since it surrounds the housing, the installation of such clips is easy. However, such clips are easily moveable and can be unintentionally removed by the user during shaving. In fact, when the clip is removed, the blade is not retained in the housing and its free movement occurs.

Various solutions have been used to avoid such drawbacks.

Patent Document 3 discloses a cartridge having a clip wound around a housing. The means is located adjacent the end of the clip. This means prevents movement of the clip ends relative to the housing in a direction transverse to the longitudinal direction of the blades to prevent mutual exfoliation of the clip ends. That means improvement. But there is still the risk of accidentally removing the clip. Furthermore, the assembly of such clips can be difficult because the blocking means must match the complementary parts of the housing.

Patent Document 4 discloses a razor cartridge in which a clip is pushed in through two openings. More specifically, each leg of the clip extends through an opening in the shaving blade cartridge. This configuration allows the clip to be held securely in place. However, it also requires different mounting requirements and significant structural modifications to the housing of known cartridges.

In order to avoid complicated assembly, US Pat. No. 5,697,058 discloses a cartridge having an annular clip with two legs that cooperate with two recesses in the housing to hold the clip.

However, the annular clip lowers the working surface, the shaving surface, during shaving.

US Pat. No. 8,286,354 U.S. Pat. No. 4,270,268 International Publication No. 9610473 Pamphlet International Publication No. 9717174 Pamphlet International Publication No. 9955499 Pamphlet

To this end, according to an embodiment of the present invention, such a shaving blade cartridge comprises a first leg of the clip surrounding at least a portion of the first longitudinal side and the bottom side of the housing, and of the clip. The second leg is characterized in that it is accommodated in the through hole.

These features allow the blade to be retained within the housing in a safe manner without lowering the shaving surface (also called the shaving window). The legs of the clip housed within the through hole allow the clip to be held securely within the housing. The legs of the clip surrounding the housing allow easy assembly of the clip. The clip provided to hold the blade does not require significant structural modifications to the existing housing, yet creates stress on the clip that can cause the clip to withstand the forces created during shaving. Easy to assemble to the housing without The embodiments of the invention disclosed herein are distinct from US Pat. No. 8,286,354. It has two pairs of openings that extend through the housing from top to bottom (each pair of openings has one opening in front of the cutting edge and one opening behind the cutting edge), and the correspondence of the openings. A pair of separate clips, each having a pair of legs extending through the pair.

As can be seen from FIG. 7, the shaving blade cartridge 1 is attached to the handle 7 extending in the handle direction between the proximal portion Pp and the distal portion Dp. The handle 7 is rotatable with respect to the shaving blade cartridge 1. In other embodiments, the handle 7 may be fixed to the shaving cartridge. The handle direction may be curved or may include one or more straight sections. The shaving blade cartridge 1 can be releasably connected to the shaver handle 7 by, for example, a lock/release mechanism.

As shown in FIGS. 1, 2 and 3, the shaving blade cartridge 1 includes a housing 9. The housing 9 extends along the longitudinal axis XX. When viewed from above, the housing 9 has a rectangular overall shape. However, in some embodiments, the overall shape of the housing 9 may be different, for example the housing 9 may have an elliptical shape. The housing 9 comprises a top surface 11, a bottom surface 13 opposite the top surface 11, and first and second longitudinal surfaces 15, 17. For example, the bottom surface 13 is configured to be located in front of the handle 7, while the top surface 11 is located opposite the handle. The top surface 11 and the bottom surface 13 may be parallel to each other. The first longitudinal surface 15 extends along the longitudinal axis X-X. The second longitudinal surface 17 and the first longitudinal surface 15 face each other. The second longitudinal surface 17 may be substantially parallel to the first longitudinal surface 15, especially if the first and second longitudinal surfaces 15, 17 are flat. The second longitudinal surface 17 also extends along the longitudinal axis XX. The first and second longitudinal surfaces 15, 17 respectively extend in the transverse direction Z between the top surface 11 and the bottom surface 13 of the housing 9 along the transverse axis Z-Z. The first surface 15 may be in front of or behind the blade edge according to this embodiment.

The housing 9 may also comprise first and second side surfaces, as best seen in FIG. 2, which, between the first and second longitudinal surfaces 19,21, intersects the axis Y-. Extending along Y, this intersecting axis YY is, for example, orthogonal to the longitudinal axis XX and to the transverse axis ZZ. The first and second side surfaces 19 and 21 are arranged between the top surface 11 and the bottom surface 13 in the Z direction. The first and second side surfaces and the longitudinal surfaces 15, 17, 19, 21 cooperate to form the outer surface of the housing 9. Both the first and second side faces 19, 21 join the longitudinal ends 23, 25 of the first and second longitudinal faces 15, 17 respectively. Similarly, both the first and second longitudinal faces 15, 17 join the free ends of the first and second side faces 19, 21.

The housing 9 may be a plastic material. However, other materials may be used. The housing 9 can include, for example, on the bottom surface 13 a connection mechanism 31 configured to connect the handle 7. The connection mechanism 31 can thus enable the release of the shaving blade cartridge 1 and/or its attachment to the handle 7.

The housing 9 also comprises a blade receiving section 33, as shown in FIG. The blade receiving section 33 or the blade receiving area can have a substantially rectangular shape. The blade receiving section 33 is arranged on the upper surface 11 of the housing 9. The blade receiving section 33 has a recess and is configured to receive at least one cutting blade 35. That is, the shaving blade cartridge 1 includes at least one cutting blade (hereinafter also referred to as a blade) 35. As shown in FIGS. 1, 2, 3, and 6, the shaving blade cartridge 1 includes three cutting blades 35. However, in other embodiments, the shaving blade cartridge 1 may include more or less than three cutting blades 35, for example, the shaving blade cartridge 1 may include five cutting blades as shown in FIG. 35. The following description refers to a drawing showing a shaving blade cartridge including three or five cutting blades 35. However, as mentioned above, the number of cutting blades may vary.

The blade 35 is mounted in the housing 9 between the first and second longitudinal surfaces 15, 17 of the housing and in the blade receiving section 33 between the first and second side surfaces 19, 21 of the housing 9. As shown in FIGS. 1, 2, 3 and 6, each blade 35 extends longitudinally along the longitudinal axis XX. Each cutting blade 35 comprises first and second ends 37, 39 along the longitudinal axis X-X. The first end 37 of the cutting blade 35 is directed toward the first side surface 19 of the housing 9, while the second end 39 of the cutting blade 35 is directed toward the second side surface 21 of the housing 9. There is. Each cutting blade 35 comprises a cutting edge 41. The cutting edge 41 extends along the longitudinal axis XX. The blade edge 41 of the cutting blade 35 is accessible on the upper surface 11 of the housing 9 for cutting hair during shaving.

For example, the cutting blade 35 may be L-shaped, as shown in FIGS. The cutting blade 35 therefore has a cutting edge 43, a guided part 45 and a bend 47 intermediate the cutting edge 43 and the guided part 45. The cutting edge portion 43 extends along the cutting edge portion axis line. Advantageously, the cutting edge axes of all cutting blades 35 are arranged parallel to each other.

In one embodiment, each cutting blade 35 is freely attached to the housing 9, as best seen in FIG. More precisely, the blade 35 is movably mounted in the blade receiving section 33. Each cutting blade 35 is supported (or held) by, for example, two elastic fingers 49 and 51. The elastic fingers 49, 51 can be molded in one piece with the housing 9 and can extend towards each other and upwardly from both side surfaces 19, 21 of the housing 9. As shown in FIG. 3, the guided portion 45 of the cutting blade 35 is slidably guided in the slot 53 provided in the housing 9. For example, the cutting blade 35 may be a supported blade having its cutting edge 41 fixed on a blade support 57 including a guided portion 45 and a bend 47. In this case, the blade support 57 is held by the elastic fingers 49 and 51.

Deforming the first and second legs 59, 107, 61, 109 to cooperate with the bottom surface 13 of the

The first and second legs 59, 107, 61, 109 may be deformed by a bending tool with an assembly clamp (not shown) that bends the clip legs in place.

The bottom of the housing 9 may also be provided with protrusions 125 in this embodiment. The protrusion 125 extends along the longitudinal axis XX and is provided especially in the center of the bottom surface 13 of the housing 9. The protrusion projects from the bottom of the housing 9 along the transverse axis Z-Z. In the mounted position of the clip 55, the first end 37 of the clip 55 is on one side of the projection 125, whereas the second end 71 of the clip is on the other side of the projection 125. To do. The protruding portion 125 can advantageously protect the clip 55 from the assembly clamp. In fact, when the legs of the clip are bent into their mounting position by the assembly clamp and then moved away or separated from the blade cartridge with the clip, the assembly clamp mis-grasps the end of the clip. Can happen (which can't straighten the clip, leading to the discarding of the entire head). The protrusion 125 does not allow the assembly clamp to accidentally grip the clip end during its removal operation, thus the protrusion 125 protects the position of the clip during the mounting step. The lower horizontal plane of the protrusion lies within a substantially similar horizontal plane of the lower section of each leg of the clip located on the underside of the housing.
